|The Eclipse P350X offers plenty of spots for fans and inside the delivery you will find one 120mm fan with 3-pin header. Overall, the case is able to accommodate two 120 or two 140mm fans at the front, one 120 or 140mm in the top, and one 120mm at the rear. As you could have guessed, this means there is enough space for a 280/240mm radiator. If you like CPU air coolers, you will be happy to know that this case according to its official specifications is compatible with high-end models with up to 160mm height. For our internal testing we have used a way bigger cooler though and didn't run into any problems.
